Streamlining

Streamlining refers to the practice of simplifying code to reduce complexity, remove redundancy, and improve readability and maintainability.

In PHP, streamlining often involves replacing verbose constructs with more expressive modern syntax: match expressions instead of switch, arrow functions instead of closures, named arguments to clarify intent, nullsafe operators to flatten nested null checks, and short-circuit assignments with ??=.

Streamlining is distinct from premature optimization: it targets structural and expressive clarity rather than micro-level performance, and its effect is measured by reduced cognitive load for the reader.

<?php

    // Before streamlining
    if ($value === null) {
        $value = computeDefault();
    }

    // After
    $value ??= computeDefault();

?>
